Abstract: PROBLEM TO BE SOLVED: To realize a semiconductor production system in which a film having a substantially uniform film thickness can be deposited on the surface of a wafer by preventing intrusion of filming gas to the rear surface of the wafer or into a wafer supporting stage. SOLUTION: A cover ring 8 is arranged on the upper surface of an outer ring 313 forming the passage 312 of inert gas, i.e., purge gas, and an exhaust passage extending in the radial direction of the wafer 1 from the circumferential edge part thereof is formed by the outer ring 313 and the cover ring 8. Purge gas is supplied toward the circumferential edge part of the wafer 1 through the passage 312 and discharged through the exhaust passage formed by the outer ring 313 and the cover ring 8 such that the purge gas recedes from the wafer 1 and the inside of a wafer supporting unit 3. Since filming gas is prevented from intruding to the rear surface of the wafer 1 or into the wafer supporting unit 3, a film having good uniformity of film thickness can be deposited on the surface of the wafer 1.
